EDWARD S. MARSHALL, OF LOUIS, MISSOURI, ASSIGNOR TO THE MISSOURI RAILWAYEQUIPMENT COMPANY, OF SAME PLACE.

TRUCK END CASTING.

SPECIFICATION forming part of Letters Patent No. 587,266, dated July 27,18 97.

Application filed April 29, 1897.

To all whom it may concern:

Be itknown that I, EDWARD S. MARSHALL, a citizen of the United States,residing in the city of St. Louis, State of Missouri, have invented acertain new and useful Improvement in Truck End Castings, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part of this specification, inwhich- Figure 1 is a side elevational view of my improved truck endcasting, parts being shown in section. Fig. 2 is an end view of myimproved casting. Fig. 3 is a fragmentary detail view in perspective ofone end of the top cross-bar. Fig. 4 is a detail View of a column-guideand a portion of the springseat. Fig. 5 is an elevational View of amodified form of end casting, showing the adaptation of the key-seat forthe column-bolt. is an enlarged end view. Fig. 7 is a detail View of thekey-seat.

This invention relates to a new and useful improvement in truck endcastings; and it consists in the construction, arrangement, andcombination of the several parts, all as will hereinafter be described,and afterward pointed out in the claims.

Generally stated, this invention may besaid to be an improvement uponthe truck end casting forming the subject-matterof United States LettersPatent No. 569, 964, dated October 20, 1896, and granted to the AmericanRailway Equipment Company, of East St. Louis, Illinois, assignee ofThomas Eubank.

In the above-mentioned patent the top cross-bar is cast integral withthe columnguides, while the spring-seat is formed separate and bolted tothe column-guides after the bolster and springs are in position.

In my invention the spring-seat is cast integral with and formssubstantially thebotw tom cross-bar for the column-guides,' while thetop cross-bar is cast separate and is adapted to be interlocked at itsends with cooperating parts upon the upper ends of the 001- v Fig. 6 7

Serial No. 634,383. (No modelfi said keys affording seats'for thereception of the heads of the colu mn-bolts,and an extendedbearing-surface across the top arch-bar, and thereby serve to retain thearch-bar in proper relation to its seat in the top cross-bar should thecol umn-bolt become broken or displaced.

In the drawings, A indicates the top archbar, B the lower arch-bar, Othe tie-rod, and D the cross tie-rod, all of usual or well-knownconstruction.

E indicates the column-guides, which are formed hollow and open at oneside,(the outer,) while the top and bottom are closed by webs e, whichare perforated to permit of the passage of the column-bolts Etherethrough. The upper ends of these column-guides are recessed ornotched, as shown, thereby forming ribs or flanges e, which areadapted-to cooperate with converse seats f in the upper cross-bar F.

G indicates ears projecting upward from the ends of cross-bar F, saidears being slotted,

' as at g, for the reception of a flattened key H, which key is formedwith a seat It, in which the head of the column-bolt is adapted to fitsnugly, so that it is prevented from turning.

Ears G are formed with strengthening webs or flanges g", the flange onone of said ears being cut-away, as at g, to permit of the passage of acotter-pin h, which is adapted to be inserted through a perforation inthe end of key II to lock said key in position.

I indicates the spring-seat for supporting the bolster-springs, saidspring-seat being cast integral with the column-guides and formingsubstantially the bottom cross-bar of the end casting, said castingbeing substantially in the form of a letter U. In the under side of thespring-seat is formed a seat for the lower arch-bar, said arch-bar seatbeing extended beyond the springseat to beneath the column-guides.

J indicates the truck-bolster, and K the bolster-springs.

In assembling the parts above described the tie-rod 0, cross tie-rods D,and lower arch-bar are placed in position. The U-shaped casting is nowplaced in position above the archbar, the arch-bar fitting snugly in theseat in the under side of the spring-seat and lower ends of thecolumn-guides. The bolster and springs are then placed in position, thesprings being seated upon the spring-seat and the bolster fittingbetween the column-guides. Pressure is now brought to bear upon thebolster to compress the springs to permit the bolster to pass below theplane of the upper ends of the column-guides, when the top crossbar mayhe slid into position, as shown in Fig. 1. After the top cross-bar issecured in position the top arch-bar is fitted in its seat in the upperside of the crossbar, and the keys II are then introduced through theirrespective slots in the ears G and secured by the cotter-pins h.Thecolunin-bolts are now insertedthat is, passed downward throughregistering openings in the key-seats, top arch-bar, webs of the column-guides, and lower arch-bar, cross tierods, and tie-rod until the headof the bolt fits snugly in the key-seat, whereby the bolt is preventedfrom turning. A suitable nut is then screwed upon the lower ends of thecolumn-bolts and turned up against the tie-rod until the parts aretightly locked against independent movement.

From the foregoing description it will be seen that an end casting isproduced which is simple, compact, and when assembled possess'es thevirtues of a one-piece casting, thus obviating the use of throughbolts;also, the key-seat, in addition to acting as a lock-nut for thecolumn-bolt, presents an extended bearing-surface for the top arch-barand serves to hold the arch-bar in its proper relation to the endcasting should the columnbolt be removed or become broken.

In Fig. 5 I have shown an adaptation of my key-seat to the form of endcasting shown in the herein-mentioned Eubank patent, wilh the additionof the strengthening-flanges for the ears G.

I am aware that minor changes in the construction, arrangement, andcombination of the several parts of my improved end casting can be madeand substituted for those herein shown and described without in theleast departing from the nature and principle of the invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is.

1. The combination with the arch-bars of a truck, of column-guides, anintegral crossbar connecting the lower ends of said columnguides, saidcross-bar comprising a springseat and being formed with a seat for thelower arch-bar, and a removable cross-bar adapted to be interlocked withthe upper ends of the column-guides, said cross-bar being formed with aseat for the top'arch-bar; substantially as described.

2. The combination with the arch-bars of a truck, of column-guides, anintegral crossbar connecting the lower ends of saidcolumnguides, saidcross-bar comprising a springseat and being formed with a seat for thelower arch-bar, a removable cross-bar adapted to be interlocked with theupper ends of the column-guides, said cross-bar being. formed with aseat for the top arch-bar, and columnbolts adapted to be insertedthrough registering apertures in the arch-bars, top crossbar andcolumn-guides, to lock said parts in their proper relative positions;substantially as described.

3.
